“RESEARCHERS at Toyama University and the National Institute of Advanced Industrial Science and Technology have invented a way of cutting up materials at the nanometre level, said the Nikkei Business Daily.”
Pretty impressive but can it juliane french-fries?
How many inches = 100 nanometres?
3.93700787402 x 10^-8 in
Ummm, I was told there would be no math.
lol you asked. 
so what is this good for??
splitting hairs 
actually, there’s 25,400,000 nanometers in one inch.
(there are a million nanometers in a millimeter, and 25.4 millimeters in an inch. 
)
edit: buh…I fail. I misunderstood the question and answered it the wrong way. But my info is still correct, if it EVER becomes useful.
I need them to make me a sword
Oh, I suck at teh math.
So would .0000039" be 100 nanometres?
If so, that is like splitting a hair 650 times!
Onyx is right on the number, but translating scientific notation owns my ass.
o rly?
ya, rly.
I haven’t had to use it since I took a math test in high school 7 years ago. (I graduated in '01, but my last math class was in my sophomore year)
but thinking back on the question at hand.
it’s 3.9andabunchofinsignificantnumbers x10^-8
that would make it 0.000000039", right?
